Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention provides an electronic device, including:

a camera module including a transmitter 10;

a receiver 20, the receiver 20 being electrically connected to the transmitter 10;

a processor 40, said processor 40 being electrically connected to said receiver 20;

a trigger 30, an input of the trigger 30 is electrically connected with the transmitter 10, and an output of the trigger 30 is electrically connected with the processor 40;

the display module 60, the display module 60 is electrically connected with the processor 40;

when the output signal of the trigger 30 in the first time period satisfies the preset condition, the display module 60 cancels the display of the image frame transmitted by the transmitter 10 in the first time period, where the working principle of the embodiment of the present invention can be referred to as the following expression:

when the camera module is in an image information collecting state, and image information (the image information includes a plurality of image frames) is transmitted between the transmitter 10 and the receiver 20, due to the existence of the electrostatic discharge signal, a part of the image frames in the image information may be interfered by the electrostatic discharge signal, so that the display effect of the part of the image frames is poor, for example, the image presented on the display module 60 may have phenomena such as flashing, jamming or jamming. Due to the trigger 30, when the processor 40 detects that the trigger 30 satisfies the preset condition, the display module 60 is controlled to cancel the display of the image frames transmitted by the transmitter 10 in the first time period. Therefore, the phenomena of flashing, blocking or deadlocking and the like in the image are reduced, and the shooting effect of the image is enhanced. Meanwhile, the antistatic interference capability of the electronic equipment can be improved.

Because the duration of each electrostatic discharge is generally 20 ns, and the duration of each frame of image is generally 30 μ s or more than 30 μ s, each electrostatic discharge generally affects only one frame of image (i.e., the image frame transmitted in the first time period is one frame of image). The display module 60 can display 60 frames of images per second, so that the display module 60 does not display the frame of images interfered by the electrostatic discharge, and the influence on the overall display effect of the images is small. In addition, after the completion of the first electrostatic discharge, it is necessary to accumulate the electrostatic charge for a long period of time as a target period of time, and then the second electrostatic discharge is performed.

Wherein, the camera module can stretch out and draw back along electronic equipment's casing, and the camera module can have the inside first state of casing that is located electronic equipment and the outside second state of casing that is located electronic equipment promptly.

In which the transmitter 10 may first transmit instruction information to the receiver 20 for indicating that the transmission of the image frame is started and then starts to transmit the image frame. In addition, the command information and the image frame may be transmitted by the same transmitter 10 and received by the same receiver 20, or may be transmitted by different transmitters 10 and received by different receivers 20.

Wherein, the output signal of the flip-flop 30 in the first time period satisfying the preset condition may refer to: the voltage variation value output by the trigger 30 in the first time period is greater than a preset value, and the specific value of the preset value is not specifically limited herein, for example: the preset value can be 150 millivolts or 160 millivolts and other values; of course, the voltage variation value output by the flip-flop 30 in the first time period is greater than the preset value, which can also be understood as: the output voltage of the flip-flop 30 changes from high level to low level suddenly in the first time period, or changes from low level to high level suddenly, and the difference between the high level and the low level exceeds a first preset value.

In addition, the output signal of the flip-flop 30 in the first period of time satisfying the preset condition may also refer to: the voltage value output by the flip-flop 30 in the first period is greater than the preset threshold. Of course, the specific value of the preset threshold is not specifically limited herein.

Specific values of the first time period are not limited herein, for example: and may be 20 nanoseconds.

The trigger 30 may be a trigger having an impedance greater than a preset impedance value, the preset impedance value may be 10 kilo-ohms, and preferably, the trigger 30 may be a schmitt trigger having a good filtering effect on the electrostatic interference signal.

In an embodiment of the present invention, an electronic device includes: the system comprises a camera module, a receiver 20, a trigger 30 and a display module 60, wherein the camera module comprises a transmitter 10; the receiver 20 is connected with the transmitter 10; the processor 40 is electrically connected with the receiver 20; the input end of the trigger 30 is electrically connected with the transmitter 10, and the output end of the trigger 30 is electrically connected with the processor 40; the display module 60 is electrically connected with the processor 40; when the output signal of the trigger 30 in a first time period meets a preset condition, the display module 60 cancels the display of the image frame transmitted by the transmitter 10 in the first time period. In this way, because the phenomena of flashing, jamming or jamming generally occur in the image frames transmitted in the first time period, the display module 60 cancels the display of the image frames transmitted in the first time period by the transmitter 10, thereby reducing the phenomena of flashing, jamming or jamming in the images and improving the image shooting effect.

Optionally, the preset conditions include: the voltage variation value of the output signal of the trigger 30 in the first time period is greater than a preset value.

The specific value of the preset value is not limited herein. For example: the preset value can be 150 mv or 160 mv.

In addition, when the voltage value of the flip-flop 30 exceeds the first predetermined threshold or is less than the second predetermined threshold, the voltage value of the flip-flop 30 may have an abrupt change. That is, when the voltage value of the flip-flop 30 exceeds the first preset threshold, the voltage value of the flip-flop 30 will become lower, and the variation value exceeds the preset value; when the voltage value of the flip-flop 30 is smaller than the second predetermined threshold, the voltage value of the flip-flop 30 becomes high, and the variation value exceeds the predetermined value. Of course, the specific values of the first preset threshold and the second preset threshold are not limited herein.

For example: when the voltage value of the trigger 30 at the first time is 300 mv (greater than the first preset threshold), and after 20 ns (the first time period) elapses, the voltage value of the trigger 30 becomes 100 mv, the voltage change value of the trigger 30 at the first time period is 200 mv and greater than 150 mv (preset value), at this time, the processor 40 may control the display module to cancel the display of the image frame transmitted by the transmitter 10 at the first time period, and as the phenomena of flashing, jamming or jamming generally occur in the image frame transmitted at the first time period, the phenomena of flashing, jamming or jamming in the image are reduced, and the image capturing effect is improved.

In the embodiment of the present invention, the preset condition is that the voltage variation value of the output signal of the trigger 30 in the first time period is greater than the preset value, so that it is more clear and convenient to determine whether the preset condition is met.

Optionally, the electronic device further includes a transmission circuit 50, an input end of the transmission circuit 50 is electrically connected to the transmitter 10, a first output end of the transmission circuit 50 is electrically connected to the receiver 20, a second output end of the transmission circuit 50 is electrically connected to the trigger 30, and the first output end is connected to the second output end in parallel.

In the embodiment of the present invention, the transmission circuit 50 is specially disposed, so that the electrical connection between the above components is more stable, and the electrical connection effect is better.

Alternatively, referring to fig. 1, the transmitter 10 includes a first sub-transmitter 11 and a second sub-transmitter 12, and the receiver 20 includes a first sub-receiver 21 and a second sub-receiver 22;

the input terminals of the transmission circuit 50 are electrically connected to the first sub-transmitter 11 and the second sub-transmitter 12, respectively, and the first output terminals of the transmission circuit 50 are electrically connected to the first sub-receiver 21 and the second sub-receiver 22, respectively;

wherein, the first sub transmitter 11 and the first sub receiver 21 are used for transmitting instruction information, and the second sub transmitter 12 and the second sub receiver 22 are used for transmitting image frame information.

Wherein, the first sub-transmitter 11 and the first sub-receiver 21 are used for transmitting instruction information, the first sub-transmitter 11 may be referred to as a low power consumption transmitter, and the first sub-receiver 21 may be referred to as a low power consumption receiver; the second sub-transmitter 12 and the second sub-receiver 22 are used for transmitting image frame information, the second sub-transmitter 12 may be referred to as a high-speed transmitter or a high-speed serial data transmitter, and the second sub-receiver 22 may be referred to as a high-speed receiver or a high-speed serial data receiver.

It should be noted that the first sub-transmitter 11 may be referred to as LP-TX, the first sub-receiver 21 may be referred to as LP-RX, the second sub-transmitter 12 may be referred to as HS-TX, and the second sub-receiver 22 may be referred to as HS-RX.

As an alternative embodiment, a sending state machine for generating the instruction information is provided on the first sub-sender 11, and a receiving state machine for identifying the instruction information is provided on the first sub-receiver 21. In this way, the sending state machine can be used for generating the instruction information, the first sub-sender 11 can be used for sending the instruction information, the first sub-receiver 21 can be used for receiving the instruction information, and the receiving state machine can be used for identifying the instruction information, so that the division of work of each component is more definite, and the efficiency is higher.

In the normal information transmission state, the status bits of the transmitting state machine on the first sub-transmitter 11 and the receiving state machine on the first sub-receiver 21 should be the same, for example: when the state bit of the sending state machine is '11', the state bit of the receiving state machine is '11'; similarly, when the state bit of the sending state machine is "10", the state bit of the receiving state machine is also "10"; when the status bit of the transmitting state machine is "00", the status bit of the receiving state machine is also "00".

When the status bits of the transmitting state machine and the receiving state machine are both "00", the transmission of the image frame information between the second sub transmitter 12 and the second sub receiver 22 is started, and when the status bits of the transmitting state machine and the receiving state machine are both "11", the transmission of the image frame information between the second sub transmitter 12 and the second sub receiver 22 is stopped. For example: referring to fig. 2, the status bits of the transmitting state machine and the receiving state machine are sequentially switched from "LP 11" to "LP 10" and finally to "LP 00", at which time the transmission of the image frame information between the second sub-transmitter 12 and the second sub-receiver 22 starts; when the status bits of both the transmitting state machine and the receiving state machine are switched from "LP 00" to "LP 11", the transmission of the image frame information between the second sub-transmitter 12 and the second sub-receiver 22 is stopped.

However, under the interference of the esd signal, the status bits of the transmitting state machine and the receiving state machine are not completely consistent, for example: referring to fig. 3, when the status bit of the transmitting state machine is "LP 00", under the interference of the electrostatic discharge signal, the status bit of the transmitting state machine is switched to "LP 11", and the status bit of the receiving state machine is still "LP 00", so that the communication between the first sub-transmitter 11 and the first sub-receiver 21 is failed, and further, the transmission of the image frame information between the second sub-transmitter 12 and the second sub-receiver 22 is failed, and the image displayed by the display module 60 is flashed, jammed or dead.

In the embodiment of the present invention, the first sub-transmitter 11 and the first sub-receiver 21 are used for transmitting command information, and the second sub-transmitter 12 and the second sub-receiver 22 are used for transmitting image frame information, so that the division between the first sub-transmitter 11 and the first sub-receiver 21, and between the second sub-transmitter 12 and the second sub-receiver 22 is more definite and more efficient.

Optionally, the transmission circuit 50 is a differential trace.

In addition, the differential trace can employ LCM, C-PHY, or D-PHY serial link communication techniques.

In the embodiment of the present invention, since the transmission circuit 50 is a differential trace, information transmitted between the transmitter 10 and the receiver 20 can be transmitted in a differential signal manner, so that the capability of resisting external magnetic field interference of the information transmitted between the transmitter 10 and the receiver 20 is improved.

As an alternative implementation, referring to fig. 1, the flip-flop 30 includes a first sub flip-flop 31 and a second sub flip-flop 32, an input end of the first sub flip-flop 31 is electrically connected to the second output end of the first one of the differential traces, an input end of the second sub flip-flop 32 is electrically connected to the second output end of the second one of the differential traces, and an output end of the first sub flip-flop 31 and an output end of the second sub flip-flop 32 are electrically connected to the processor 40, respectively.

The transmission circuit 50 may include a first trace and a second trace connected in parallel. The first trace may also be referred to as a first sub-transmission circuit 51, and the second trace may also be referred to as a second sub-transmission circuit 52.

In the embodiment of the present invention, since the information between the transmitter 10 and the receiver 20 is transmitted in the form of differential signals, the transmission circuit 50 may include a first trace and a second trace connected in parallel, and one of the first trace and the second trace is used for transmitting high-level signals, and the other is used for transmitting low-level signals. In this way, no matter the electrostatic discharge signal is an interference high-level signal or an interference low-level signal, the electrostatic discharge signal can be detected by the first sub flip-flop 31 or the second sub flip-flop 32, so that the detection result is more accurate.

Optionally, the electronic device further includes a flexible circuit board, and the transmission circuit 50 is disposed on the flexible circuit board.

The size and shape of the flexible circuit board are not particularly limited herein. For example: the flexible circuit board may be a rectangular circuit board or an arc-shaped circuit board.

step 401, acquiring an output signal of a trigger 30 of the electronic device;

step 402, when the output signal of the trigger 30 in a first time period meets a preset condition, controlling the display module 60 of the electronic device to cancel the display of the image frame transmitted by the transmitter 10 of the electronic device in the first time period.
